You have me drooling and cursing at you in my head all at the same time. Dang it Fred!!! so excited to see what you release these at. Are you going to do a parts only option or as a full unit with core charge?
I am not sure yet, but I am to do it ala carte. Some folks don't want or need the R&P. Some might want the Celica 6th gear.You have me drooling and cursing at you in my head all at the same time.

What price range will this upgrade be? Have you tried adding a oil cooler to see if the gearbox will last longer?At BWR we’ve been frustrated with the Lotus transmission since 2006. As we add power and grip the C64 transmissions break. It is pretty robust given that it was designed for far less power than the forced induction.
We'll see on price once we get the protos finished. Temperature is not the problem. The breakages have been material/design failures. Not so say that adding a cooler wouldn't be a good idea for an endurance racer, just not what has been the issue thus far.What price range will this upgrade be?

One question, however. Now that you are making 1st and 2nd into usable gears for us road course junkies, shouldn't you make them wider for durability? First gear drive gear is likely next up on the list of failure points once we start using it more often.
Ok I'm gonna weigh in.
I still think that my ideal transmission would be a stock C64 with the C66 final drive (3.941). That gives a better spread for the big forced induction cars.
This would yield these mph's @ 8500 redline in each gear on stock tires:
Stock: 43, 66, 91, 116, 148, 166 (~3000 @ 60mph in 6th)
C66 final: 49, 76, 105, 133, 170, 191 (~2600 @ 60mph in 6th)
This lets you do the following to the gears...
1st: May actually be useful since it's a bit taller
2nd: Reach over 60mph
3rd: Reach over 100mph
4th: Let's you run the quarter mile without shifting into 5th... :drool:
5th: Reach over 150mph in 5th - one should never see redline here :crazyeyes
6th: Lowers rpm on the highway for "economy"
If something like this was made with nuclearized components I'd buy one in a heartbeat.
So... what are the actual gear set ratios of your proposed box?
Nope - back in 2011 I was running EFI with a 9160rpm redline AND 245-45-17 Nitto Drag Radials (with my stock pegleg C64). I managed these speeds at redline:If you run 25" i.e. 255/40R17 you are right at 125mph. Either is probably good enough for 1/4 mile?
I was just referring to the final drive, not the horrific drive gear ratio selection of the C66.The C66 gearing is that it isn't good for track folks.
Ahhh... That's why it's so FuZzyDave, with your tall tires, you have headroom in 4th mph-wise for the 1/4.
The Ratios aren't disclosed yet because they may change slightly over the prototyping phase. All will be made known in due time.
